It is a 100pF 1K Through-Hole Silver-Mica Film Capacitor. The capacitor contains an insulator between relative conductors in an electrode. Non-inductive construction using metalized Silver Mica film with flame-retardant epoxy resin coating.

Features:

1.  Non-inductive, epoxy Silver Mica coated, high moisture resistance.
2.  The dissipation factor is normally low and it is stable against high frequency and change of temperature.
3.  Recommended for high-frequency circuits like an s-curve compensating circuit.
4.  High reliability because of its excellent Self-Healing performance.
